Accredited EV Testing in Brazil—Replication Package (MDS-1..4, Instrument S1, Code_S1.ipynb)

Open replication package for the study of accredited laboratory readiness for on-road electric mobility in Brazil (ICS 43.120). The package contains four CSV datasets (MDS-1..4), the full survey instrument (Instrument S1, PDF/DOCX), and an executable Jupyter notebook (Code_S1.ipynb) to reproduce the Accredited Coverage Index (ACI) and the weighted index (wACI). The indicator denominator is N=69 (after identical-text deduplication by edition). Using the September 08, 2025 RBLE snapshot, ACI = 2.90% (2/69) and wACI = 3.62%. MDS-1 documents component/domain tagging and IDT groups; MDS-2/MDS-3 provide dated RBLE snapshots with coverage states and clause lists; MDS-4 is the per-standard indicator table with coverage flags and weights. All CSVs are semicolon-delimited (latin1). Data are CC BY 4.0; code (Code_S1.ipynb) is MIT-licensed (see LICENSE). The README and data dictionary describe keys, joins, and reproduction steps.
